Bees are exposed to several threats, including pathogens (i.e. Nosema ceranae), pesticides and environmental contaminants. The new insecticide flupyradifurone, and the microplastics in the environment, have raised significant concerns on bee health. This study evaluated the simultaneous effects of microplastics, flupyradifurone, and N. ceranae on honey bee health, focusing on survival rates, N. ceranae replication, daily food consumption, and bee midgut histological alterations. Results showed a significant decrease in bee longevity across all treatments compared to the control, with the combination of flupyradifurone, microplastics, and N. ceranae having the most severe impact. Microplastics and flupyradifurone exposure also increased N. ceranae proliferation, especially in bees subjected to both stressors. Histological analysis revealed reduced regenerative cell nests in the midgut and changes in the nuclear matrix, indicating stress responses. Overall, the simultaneous presence of both biotic and abiotic stressors in nature can synergistically interact, leading to harmful effects on bees.
蜜蜂面临着多种威胁，包括病原体（如蜂球囊菌）、农药和环境污染物。新的杀虫剂氟吡呋喃酮和环境中的微塑料对蜜蜂健康引起了极大的关注。本研究评估了微塑料、氟吡呋喃酮和蜂球囊菌对蜜蜂健康的同时影响，重点关注存活率、蜂球囊菌复制、每日食物消耗和蜜蜂中肠组织学变化。结果表明，与对照组相比，所有处理组的蜜蜂寿命都显著降低，而氟吡呋喃酮、微塑料和蜂球囊菌的组合则产生了最严重的影响。微塑料和氟吡呋喃酮的暴露也增加了蜂球囊菌的增殖，尤其是在同时受到两种胁迫源的蜜蜂中。组织学分析显示中肠再生细胞巢减少和核基质变化，表明存在应激反应。总的来说，自然界中生物和非生物胁迫源的同时存在可能会协同相互作用，对蜜蜂产生有害影响。
